Description

MariaDB/MySQL

CREATE TABLE country (id   int, name varchar(20));

insert into country values (1, 'India');
insert into country values (2, 'Russia');
insert into country values (3, 'USA');

Hive

CREATE EXTERNAL TABLE country (id int, name varchar(20))
    STORED BY 'org.apache.hive.storage.jdbc.JdbcStorageHandler'
TBLPROPERTIES (
    "hive.sql.database.type" = "MYSQL",
    "hive.sql.jdbc.driver" = "com.mysql.jdbc.Driver",
    "hive.sql.jdbc.url" = "jdbc:mysql://localhost:3306/qtestDB",
    "hive.sql.dbcp.username" = "root",
    "hive.sql.dbcp.password" = "qtestpassword",
    "hive.sql.table" = "country"
    );

INSERT INTO country VALUES (8, 'Hungary');
SELECT * FROM country;

Expected results

ID	NAME
1	India
2	Russia
3	USA
8	Hungary

Actual results

ID	NAME
1	India
2	Russia
3	USA

The INSERT INTO statement finishes without showing any kind of problem in the logs but the row is not inserted in the table.

Running the test it comes back green although the following exception is printed in the System.err (not in the logs).
